He folded the letter to put it back in the envelope, and Ned caught a glimpse of the name Wright & Johnson, New York, before Frank put the epistle into his pocket.

"See you later," called Frank to his chums, as he hurried from the post-office.

The three boys stood staring at one another as Frank walked out. It seemed so strange they could not understand it. Ned spoke of having noticed the name of the lawyers on the envelope; the same firm that had written to Frank before.

"I can't understand it," declared Bart, as he and his chums went out, in time to see Frank mounting the steps of a building opposite the post-office, where Judge Benton had his office.

"I don't know's it's any of our affair," put in Fenn. "Only I'd like to help Frank if he's in trouble."

"So would I," spoke Ned.

"Shall we wait for him?" asked Bart.

"It's hard to know what to do," declared Ned. "If we go away he may think we're mad. If we stay he might imagine we're trying to find out what Judge Benton wanted him for. However, I guess we'd better wait for him a little while."

They did not have to wait long. Frank came out, and he seemed more cheerful than he had been in some time. It appeared as though something, that had been troubling him, had been settled to his satisfaction.

"Glad you waited," were Frank's first words as he joined his chums. "I've got an idea."
